Fox doesn't even watch their own coverage! There was a briefing just an hour or so ago regarding the incident of shooting thugs on the bridge by NOPD. The NOPD officer laid out the specifics of the event, yet Fox has someone on now and the interviewer still asking questions and doesn't know the specifics. All she had to do was tune in to her own news channel, right?
That's why I watch CNN for coverage of situations of this kind. Fox is does a better job on panels of commentators and political discussion. But CNN does the best job of covering large amounts of data. Fox just doesn't have the necessary resources.
People inside the disaster area have the least information about the current situation. They do not have power and most if not all communications networks have been destroyed. That usually also applies to the police and local Emergency Management personnel.
After hurricane Ivan we were without power, phones or, cable for four weeks. Luckily Verizon's local cell phone tower survived and I could charge my cell phone from my car battery. Relatives in New Mexico and Arizona watched CNN and relayed their reports to me via cell phone. I could then inform my neighbors of the situation in our local area. The news networks are the best possible source of information after a disaster. If Homeland Security doesn't make use of that resource they are not doing their job.
